Frequently Asked Questions
Is my data safe?
Yes. All encoding, hashing, and encryption operations run entirely in your browser. Your data is never sent to any server.
Can I use this for passwords?
We recommend using the Password Generator for creating secure passwords, and Bcrypt Hash for storing password hashes. Never store plain-text passwords.
What hash algorithms are supported?
The Hash Generator supports MD5, SHA-1, SHA-256, and SHA-512. For HMAC signatures, use the HMAC Generator.
